Abstract
A method and optical system for preemptively correcting a potential future misalignment of an optical communication beam between a plurality of free space optical (FSO) units or Light Fidelity (Li-Fi) units by intentionally generating predetermined and repetitive motions of the beam path between the units using an adjustment mechanism. In some examples the predetermined motion is a circular motion or a reciprocating and/or translating motion. The predetermined motions can be implemented by an adjustment mechanism which can include a plurality of piezoelectric actuators or one or more MEMS controlled mirrors or micro-lenses.
